Description
An ASP .NET application must enable custom error pages in order to prevent attackers from mining information from the framework's built-in responses.
Common consequences
- Confidentiality: Read Application Data
Mitigations
System Configuration — Handle exceptions appropriately in source code. ASP .NET applications should be configured to use custom error pages instead of the framework default page.
Architecture and Design — Do not attempt to process an error or attempt to mask it.
Implementation — Verify return values are correct and do not supply sensitive information about the system.
